APPARATUS FOR UTILIZING EXHAUST-STEAM.

SPECIFICATION forming part of Letters Patent No. 226,850, dated April 27, 1880.

Application filed December 22, 1879.

haust-steam in the right-hand-side compartment of the cylinder g g are gear-wheels for imparting the motion of the cylinder B. h is a screw, by which the cylinder 0 is fixed in its immovable position. 'iis driving gear from the steam-engine. 7c is the stufiing-box of the shaft 1, and la connecting-pipe between the steam-boiler and the cylindrical tank A. m m are round bolts on the slide-plate D, which are fitted in the wall of the cylinder 0. n is a vertical shaft to produce the revolution of the cylinder B. 0 is a small steam-outlet from the right-side chamber of the cylinder 0 into the space between the two cylinders B and O. p is the openingfor the slide-plate, and broader than the thickness of the plate, so as to allow the entrance of the water coming from the steam-boiler into the left chamber of the cylinder G. qis a long narrow slit in the surface of the cylinder B, for admitting water from the boiler, and through which. the expanded exhaust-steam, together with the water, is ejected by the motion of the slide-plate D. This slit is nearly as long as the whole length of the cylinder B, and does not touch the outlet-slit 0. r is a stuffing-head, which, by the pressure of the water of the boiler, at all times renders the cylinder (3 steam-tight.

The flanges of the cylinder B are exactly adjusted with the cylinder 0, and the whole weight is supported by the pipe 0 and the stud d on the supports a and l).

The length and diameter of the apparatus are found, so that the area of the right side of .the cylinder 0 and the space between the two cylinders B and 0 allow the expansion of the exhaust-steam to one atmosphere.

The operation is as follows: The exhauststeam enters by the pipes e and c and the holes f and 0, and finds in the right-side chamber of the cylinder and, further, between the two cylinders B and C, Fig. 2, a free space, which Be it known that I, DANIEL GRIMM, of Nuremberg, Bavaria, Germany, have invented a new and useful Improvement in Apparatus for Utilizing Exhaust-Steam, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a longitudinal section of a cylindrical tank with the apparatus therein. Fig. 2 is a transverse section in line as .70, Fig. 1. Fig. 3 is a horizontal section. Figs. 4, 5, and 6 are different positions of a revolving cylinder within the apparatus, and the reciprocal positions of a sliding plate within an immovable cylinder.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in an apparatus by means of which the exhausted steam from steam-engines is reconducted by mechanical operation into the water of the steam-boiler, so that it may be repeatedly used.

Referring to the drawings, A represents a small cylindrical tank, communicating with the steam-boiler by means of the conductingpipes l. B is an eccentricallyarranged cylinder, revolving steam-tight around the immovable cylinder 0, which is supported by the stud d, and the steam-conducting-pipe c, which at the same time serves as a fulcrum to the cylinder B. D is a sliding plate which passes diametrically through the cylinder G, and in all its positions slides toward the inner surface of the revolving cylinder B, the water entering from the steam-boiler into the cylinder B, and its conduction into the cylinder 0 causes the sliding plate D to be pressed steamtight to the right-hand side of the apparatusthat is to say, to the partition-dividing the whole cylinder Gin two equal parts. The slideplate is packed in any suitable manner. The supports a I) bear the stud (I and the conducting-pipe c, on both of which revolves the cylinder B.

c is an imuiovably-fixed conducting-pipe, connected with the cylinder 0, serving for the from the engine. cl is a supporting-stud to the cylinder G. e is a steam-pipe connecting with f is the inlet-hole of the exon the other side by the stuffing-head r, so that it can expand to one atmosphere of pressure.

With a continued revolution in the direction of the arrows this space for the exhauststeam will continually enlarge and be closed by the slide-plate D, Figs. 2, 4, and 5, and the stuffing-head r, tillthe revolution will be at one side is closed by the slide-plate D, and
